Application filed November 19, 1919. Serial No. 339,147.

To all whom it may concern Be it known that I, ALFRED WILD, a citizen of the present Government of Czechoslovakia, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Weaving-Machines, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

The present invention relates to certain new and useful improvements in weaving machines and refers more particularly to a machine of this type especially adapted for use in'weaving baby carriage bodies, hoods and any other goods =made of reed, fiber or any other materials.

Heretofore it has been the general custom to weave the material and then cut the woven material into shape and tack the same upon a body form or else to weave the same by hand upon the body form. This manner of constructing baby carriage bodies is unsatisfactory in that the same is very expensive necessitating the work of several men for each body and necessitating an unnecessary amount of time in construction.

With these and other inherent objections in mind my invention has for its primary object to provide a body weaving machine which will weave the complete body direct upon the body core or form and which will be automatic and require the attention-of but one operator, thereby greatly reducing the cost of production as well as decreasing the amount of time at present necessary to produce a completed baby carriage body.

Another ,object of this invention is to provide a baby carriage body weaving machine which may be entirely automatic in its operation and which may be manually operated if it is so desired.

A further object of the present invention is to provide a baby carriage body weaving machine which will operate with either reed, fiber, or any other desired material without 'breakageas the war guiding tubes which extend to a point ad acent the topmost weft insures the smooth operation of the upper filling strand or weft being interwoven irrespective of the roughness of the warp.

A still further object of the present invention is to provide means for pressing the weft into place after the same has been interwoven between the warp and to also provide means for mechanically or electrically operatlng the warp carrying guide tube members as hereinafter described.

1th the above and other objects in View WlllCh will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts, substantially as herinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.

In the accompanying drawings I have illustrated two complete examples of the physical embodiment of my invention constructed according to the best modes I have so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a side plan view of a baby carriage body weaving machine embodying the features of my invention.

Fig. 2 is a top plan view thereof.

Fig. is a sectional View taken transversely through one arm of thesupporting frame on the line 3-3 of Fig. 2.

Fig. 4 is a fragmentary detail view taken (in the plane indicated by the line 44 of ig. 5 is a partly diagrammatic view illustratmg my invention as adapted for operation by a plurality of electric magnets, and Fig. 6 is an enlarged detail view of one of the block members.

Referring now more particularly to the The frame 10 may be of various shapes ac- I cording to the type for which it isespecially designed and has mounted thereon two series of'block members 13 secured to the top face of the channel irons 11 by suitable fastening means 14, see Fig. 3.

The inner ends of the blocks 13 of each series are arranged in spaced relation to provide an intermediate channel 15 extend ing around the frame and normally disposed centrally of the channel 15 are a lurality of warp guide tube carrying mem ers 16. 16 is carried by each adjacent pair of blocks 13 of the two series and is movable One warp guide tube carrying member and having a washer orcollar secured thereto between which and the outer wall of bore 18 a spring 21 is confined. By this structure the member 16 is normally urged to a )osition centrally of the channel as will be at once seen, the head 20 preventing the rod 19 or spring 21 of one block from projecting into the channel 15 when the member 16 is urged into the recess 17 1 of the adjacent opposed block by the means to be later descri ed.

In operation a flat woven portion of ratan members woven together and preferably se-' cured to a board (not shown) used as a base member which is in turn secured to the under side of a body form of core 22 which is then mounted upon thetop of a jack screw 23 adjustably carried by a tubular supporting standard 24 and is engaged by a threaded nut 25 provided with peripheral I ratchet teeth 26 for automatically lowering the jack screw and consequently the body 22, as will be later described. The warps 27 of the flat woven material secured to the underside or bottom of the core 22 are dis posed within warp guiding tubes 28 having their upper ends secured to the members 16. The uide tubes 28 have flexible portions 29 ad acent their-point of connection with the members 16 whereby the movement thereof is unhindered.

Disposed about the inner series of blocks 13 is a track 30 shaped to correspond with that of the frame 10 to'the inner channel 11 on which it is secured by bracket arms 31, see Fig. 3. Movably mounted on the track 30 is an operating motor 32 mounted upon a support 33 in which is mounted a horizontal shaft 34 in gear connection with the motor 32 and a vertical shaft 35 in gear connection with the shaft 32. Freely journaled upon theshaft 35 are two sets of guide wheels 37 and 38, the wheels 37 engaging the outer face of the track 30 and the wheels 38 engaging longitudinal edges thereof, and two guide wheels 39 engage the rear face of the track 30 and thus freely movably mount the support 33 upon the track.

In order that the carriage 33 may be moved about the frame 10 a gear pinion 40 is fixed upon shaft 35 and is in mesh with a gear rack 41 secured to the outer face of the track 30.

Secured to the carriage 33, as at 42, is an arm 43 which projects over the channel 15 between the sets of blocks 13 and has mount- 28. The guide tube 44 is capable of a slight lateral swinging movement by reason of the flaring opening 45 in which it is secured but is rigid against the longitudinal swinging movement.

Secured to the housing of motor 32 is a supporting'shaft 46 for a drum or spool 47 upon which is wound the weft 48 which extends downwardly through the guide tube 44 and is interwoven between the warp 27 in the manner hereinafter described.

Each member 16 has a roller 49 j ournaled on its upper base having a central aperture therein communicating with the guide tube 28 which rollers are adapted to be engaged by a cam member 50 which is journaled upon the weft guiding tube 44. The cam 50'is adapted to be rocked by means of a'pitman or connecting rod 51 having one' end secured to the cam member as at 52 and its other end secured to a crank pin 53 carried by a disk of the cam and the next member 16 will he moved to the right. With the warps 27 which are carried by the members 16 by their guide tubes 28 the weft 48 is laid between the warps and as the carriage 33 progresses the members 16 are alternately moved first in one direction and then in another.

When the carriage 33 has reached one end of the track 30 it is reversed and travels back over the track again alternately moving the members 16 in opposite directions and disposing the weft therebetween to accomplish the weaving as will be obvious. 1 In order that the weft 48 will alternately engage the opposite sides of each warp, I em-' ploy an uneven number ofwarps and the ef fect will be that each end warp will have the weft coiled thereon. In order to insure the topmost weft engaging the warp thereunder I provide a presser finger or wheel 56 which is carried by the carriage 33 or the guide tube 44 and presses the same down as best shown in Fig.1.

As it is necessary I to drop or lower the core 22 the distance of the thickness of the weft after each complete operation of my device I provide a bell crank lever 57 pivoted to the standards 12 and having its lower end engaged with a'slidably mounted bar 58 having a dog 59 engageable with the ratchet teeth 26 of the nut 25, the upper ends of arms 60 formed on said bell crank lever are en? gageable by the carriage 33 when it reaches either limit of movement to rotate the nut 25 and consequently lower the core 22.

At each end of the track 30 I provide a stop 61 to prevent the carriage 33 fromrunning thereoff, and said stop has a reversing switch 62 carried thereby for reversing the direction of rotation of the motor 32 when the carriage engages the stop, and as this specific structure forms no important part of my invention except in the combination set forth, the same has only been shown without its electric connections In place of the cam 50 for moving the members 16 in opposite directions to accomplish the weaving of the weft with the warps, I may employ electromagnets 63 as best shown in Fig. 5, the magnets of every other block 13 of one series having their positive ends connected by a wire 64 with a switch 65 disposed at one end of the track 30 and the negative ends of the magnets of the blocks 13 opposite the members as having their positive ends connected by wires 64 are connected by a wire 66 leading to another point of the switch 65. The positive ends of the magnets intermediate the magnets having their negative ends connected by the wire 66 are connected by a wire 67 with the wire 64 and the negative ends of the magnets opposite the magnets having their positive ends connected by a wire 67 are connected with the wire 66 by a wire 68. By this construction the members 16 will be staggered as depicted in Fig. 5 when the switch 65 is closed and thus the carriage 33 may be run around the frame 10 at a greater speed than with the structure hereinbefore described and when the same reaches the end of the frame oppositethe end having a switch 65 the same enga es a switch similar to switch 65 (not shown reversing the connections with the magnets 63 and oppositely staggering the members 16 so that the carriage 33 may-run around the frame and dispose the weft 48 properly between the warps.

From the fore oing description taken in connectio with tfie accompanying'drawings, it will beat once apparent that I provide a comparatively simple machine for. weaving baby carriage bodies or the like and that by providing the guide tubes 28 for the warps the same may be employed for any kind of material as the warps 38 have their outer ends smooth-andthus no friction is caused by the weft sliding therebetween. It will also be seen that I weave direct upon the body form whereas heretofore the material has been woven separately and then shaped and 1.
